The OP doesn't have a crystal ball. She obviously had to leave the house earlier than her baby normally has it's first feed, in order to be at the hospital on time.
She tried to bf her baby before leaving, but the baby wouldn't bf. There is no way you can 'force' a demand-fed bf baby to feed if they are not ready for a feed. They just won't feed. What was she supposed to do, shove her nipple in the baby's mouth, squeeze until milk came out, and hold the baby's nose until he swallowed FFS?!
Is that seriously what you are all saying?!
She did what she could - she left her 4yo DD AT HOME with her mum. She brought her Aunt who lives quite a way away to look after the baby.
She obviously didn't go there WITH the intention of taking the baby on the ward, or she wouldn't have bothered to arrange for her Aunt to look after him in the waiting room.
They were waiting a while in the waiting room, baby woke up and wanted to be fed. So the OP started feeding. The nurse chose that particular moment to call them into the ward to start the paperwork. Sod's law in action.
How many stories have there been on MN about people having to answer the door to the postman or whoever, with a baby stick to their boob? Loads.
So the OP asked if either they could wait till she had finished feeding (told no due to it delaying the op meaning that her DS would lose his 'spot' in theatre), so the general assumption would surely be that if baby is bf and has already started the feed, baby goes with mum until feed is finished and then be taken off the ward.
I can't see what else the OP could possibly have done. She couldn't have done any more, and obviously this hospital ISN'T as bf friendly as it wishes to be if it's going for some award or something about being the most bf friendly hospital in London.
And of they ARE going for that award, then why is it wrong for the OP to email them to let them know that actually, one of their policies ISN'T bf friendly, which gives them an opportunity to make a change to the 'rules' that are not bf friendly.
I can't see the issue with that, tbh. And I think the personal digs aimed at Star are out of order tbh.
